OK, so I started thinking about the "why" of what you're doing and I'm 
not sure what your goal is.  If you get all the data on all the channels 
when you disable cross-source EIT, then I'm assuming you're only 
enabling cross-source EIT in hopes that it will do EIT scanning more 
efficiently (only having to scan one video source or only having to use 
one card for EIT scanning or whatever).

If that's the case, there are some planned improvements to the EIT 
scanner that should make EIT much more efficient than the current "scan 
everywhere all the time" approach.  It will give the same type of 
benefits as http://svn.mythtv.org/trac/ticket/5754 , but with a 
different (and simpler) design.
